Me, too.

Thanks for this hint. Actually it tests for the lowercase name
(parmetis_v3_partkway). If I use that one in repartition.hh, then it
works. The reason why this worked with METIS/ParMETIS is that they
detect C++ and use extern "C" in the header, while scotch does not do
that. I will fix it.
